ATTORNEYS Patented June 6, 1933 UNITED STA TES ALFRED J. CHAMBERLAIN, OF MILWAUKEE, WISCONSIN PLURAL GOMPARTMENT RECEPTACLE Application filed March 13, 1931. Serial No. 522,218.

This invention relates toan improvement in plural compartment containers of the type especiallydesigned and adapted for the shipment of paints or the like of the character wherein it is essential to preserve the pigment and vehicle unmixed until the paint is actually to be used. One example of such a paint is aluminumpaint. If such paint is mixed at the point of manufacture and then stored and shipped the pigment or aluminum powder will settle and solidify. This characteristic of such paint makes it necessary to ship the ingredients separately and mix them at the point of use.

Among the principal objects of the invention are to simplify the construction and the 1 problem of manufacturing containers of this type and yet produce a superior sealing action as between the cover or main outer container and as between the interiors of the inner and outer containers.

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims; reference being had to the accompanying drawing, forming a part of this 7 specification, and in which:

Figure 1 is a perspective view showing a plural compartment container embodying the present invention, parts being broken away for the sake of illustration;

Figure 2 is a fragmentary view invertical section showing the container construction of Figure 1 with the parts shown in sealed position; and

Figure 3 is a fragmentary view similar to ,7 Figure 2 but showing the parts prior to assembly and sealing.

Referring to the drawing, the numeral 1 designates an outer container having a bottom 2 seamed thereto as at 3. The upper end of the container is reduced as at 4 and the reduced upper end is provided with an outwardly and downwardly inclined flange 5, the upper surface of which is flat to afford a gasket seat and the edge of which is formed with a reinforcing bead. 6. Adjacent the reduced upper end l the container is provided with an inwardly directed corrugation or ledge 7 extending around its entire inner circumference and affording a second gasket seat. 7 An inner container 8 is provided and has a body portion 9 and an integral bottom 10. The upper end of the body portion 9 is formed with an outwardly directed rolled bead or annular shoulder 11. The inner container 8 is of a shape and size to fit within the outer container in such manner thatthe inwardly directed ledge 7 of the outer container 1 is in supportingrelation to the outwardly directed shoulder or head 11 of the V inner container 8. A tubular gasket 12 of annular form is interposed between the ledge 7 and shoulder 11 and when appropriately compressed seals off the interior of the outer container 1 from the interior of the inner .a container 8. y A cover or closure designated generally at 15 is provided and is designed to serve both the inner and outer containers. This closure 15 has a cupped body portion 16 and an outa wardly and downwardly directed annular flange 17. To the underside of the flange 17 a gasket 18 is applied. and is held in position by retaining clips 19 formed integral with the flange 17. These clips 19 are located in between bendable sealing lugs 20 which are also integral with the flange 17 and which are designed to be bent up under the flange 5 of the outercontainer in the manner shown in Figure 2 whereby the cupped body portion of the closure 15 is forced down into theupper reduced end 4 of the container 1 and the gaskets 18 and 12 are appropriately compressed; It willbe noted that the gasket 18 is compressed between the inclined gasket seat afforded by the flange 5 and between the inclined cover flange 17. The underside of the cupped body portion 16 of the cover bears directly on the crest of the rolled bead 11 and forces it downwardly toward the inwardly directed ledge 7 thereby compressing the gas- 93 ket 12 and setting up an effective sealing engagernent between this gasket and the ledge 7 and the head 11.

In use the vehicle is contained in the outer container 1 and the pigment or powder in 2 the inner container 18. When the cover 15 is applied and the sealing lugs 20 bent up under the flange 5 the gaskets 12 and 18 are compressed in the manner shown in Figure 2 and the inner container is firmly held in position.

The sealing lugs 20 have hooked lower ends 25 which enables them to be pried out by a screw driver or the like when the contents of the container are to be used. This does not impair their capacity for re-sealing and this re-sealing is equally effective as to both the inner and outer containers.

With this organization a plural compartment receptacle is provided which lends itself to economical and easy manufacture and which ai'l'ords in use a highly effective seal not only between the interiors of the inner and outer containers but also between the cover and the outer container. T he seal between the cover and the outer container is of such character that distortion which occasionally occurs in shipment increases the effectiveness of the seal. All of these advantages are had without employing any elabo' rate or expensive construction; in fact, the receptacle consists, aside from the gaskets, of only three major parts, that is, the inner and outer containers and the cover.

The invention claimed is:

1. A plural compartment receptacle comprising an outer container having a reduced upper end formed w1th an outwardly and downwardly directed flange afliording a gasket seat, said outer container having an inwardly directed corrugation adjacent the reduced upper end affording a second gasket seat, an inner container having an outwardly directed shoulder around its upper end, a gasket interposed between the second gasket seat and said outwardly directed shoulder, a cover having a cupped body portion designed to fit in the upper reduced end of the outer container and to engage the upper end of the inner container to cause the shoulder to compress the gasket between it and the corrugation, said cover also having an outwardly and downwardly inclined flange provided with sealing lugs adapted to be bent up under the flange of the container and a gasket interposed and compressed between said flanges.

2. A plural compartment receptacle comprising an outer container having an inwardly directed corrugation adjacent its upper end, an inner container having an outwardly directed shoulder at its upper end, said inner container being adapted to fit within the outer container with the corrugation of the outer container in supporting relation to the shoulder of the inner container, a gasket interposed between the shoulder and corrugation, a cover for closing the upper end of the outer container and having a portion engageable with the inner container to force the inner container downwardly and cause the gasket to be compressed between its shoulder and the corrugation when the cover is secured in position, cooperating gasket engaging flanges on the cover and outer container, a gasket interposed and compressed between said flanges and means for securing the cover to the outer container with the flanges compressing the gasket and the cover forcing the inner container downwardly.

3. A plural compartment receptacle comprising an outer container having an inwardly directed eircumferentially extending corrugation adjacent to but spaced from its upper end, an inner container fitted within the outer container and having an outwardly directed annular shoulder, a gasket interposed between the corrugation and shoulder whereby the inner container is supported on and within the outer container and yet the interiors of said containers are effectively isolated, a cover cooperable with the inner container to cause the gasket to be compressed between the shoulder andcorrugation and means between the cover and the outer container for securing the cover in position and effecting a seal between the cover and the outer container.

4. A plural compartment receptacle comprising inner and outer containers and a single cover for both containers, said inner and outer containers having interengaging parts located within the outer container and below the rim thereof for supporting the inner container and for sealing off the interior of the outer container from communication with the interior of the inner container and cooperating means on the cover and outer container for securing the cover in position and effecting a seal between the cover and the outer container.

In witness whereof, I hereto aflix my signature.
